Elective foot surgery: relative roles of doctors of podiatric medicine and orthopedic surgeons.

We examined the roles of Doctors of Podiatric Medicine (DPMs) and orthopedic surgeons in the provision of foot surgery by analyzing the 1982 computerized claims of over 1.1 million federal employees, retirees, and family members. We found that DPMs provided over 60 per cent of all elective insured foot surgery. Without being able to adjust for the severity of the patient's underlying condition or the appropriateness and outcome of the surgery, the average per procedure charge submitted by an orthopedist was 17 per cent higher than that of a DPM; orthopedists were five times as likely to perform a procedure on an inpatient basis, and admitted patients to a hospital had longer stays; DPMs perform a greater number of procedures per episode, but their overall charges during the average foot surgery episode were 30 per cent lower, primarily because of their lower hospitalization rates. The possible impact of recent changes in health care delivery on the DPM/orthopedist practice comparison are discussed as are several questions regarding the quality and need of the care provided by these two groups.
